I see a missed opportunity for an FR-badge on that treadmill; front and center.
Good catch, C.D.Y. It took <15s to determine the opportunity was not worth the investment. When deciding... zoomed in and saw the following; subtle but real-life:
Angular changes
Aspect Ratio changes
Hue changes
Gross shadow/reflection/refraction
Half-pixel movements in hard to badge areas
So estimate for badging this clip (very desirable);
with 150 frames for 16.19s
at size:320 x 403 Pixels (0.79)
and color:256 (8 BitsPerPixel)
was not enticing at all.
That is, this clip required 8 minutes to prepare for FR post.
With badging, It would take over 1 hour (a limit)
and not look 'good' enough for quality control.
Baby steps.
Make it a great day.
